To all whom t2 mayconeern." l v L Y Beit known that I, yCHARLES I.SiroLoFF, a ,citizenA` of the United States, and resident of New Yorkcit inthe county of New York and Staten New York, havel invented certainnew and'v fusetul Improvements in Saliva-Ejectingy Devices', ofv whichthe fol- This inventionrelates toy improvements in the means forejecting saliva from the mouth during dental and surgical operations,-and more' Y particularly to that typel of salivaeje'cting device whereinthe sucti'onpressure v created by a vacuum producing apparatus isutilized, as' the ejecting medium.A

I An object of my invention is to provide Va tion, aiiiordin'g thehighest efciency of functioningr for the existent suctionv pressure.

"pr`es`sure', when this pressure! isWea'l, `isV a i That is', by reasonof its refinement: and simplicity of construction, the loss 'of suctionminimum. Furthermore, through the pro-4 '.vision of a pressureregulating" attachment,

the suction pressure may also be decreased, at

will, should it prove great "enough to causeV discomfort.

notlier'object of' my invention is the provision of a positive means ofc'onnectionbetween the mouth-piece andmain body yof fthe device,r'zvhich".v means ailso provides ,piaga-inst unintentional.disengagement of the i said mouth-piece andl body. further ob-V ject isthe provision of a rubber guard to eliminate the unpleasant Jfeelingcaused by theY direct contact between the mouth-piece l and teeth.

i -Other objects Aof this invention, not -here= A inafteparticularlyenumerated, will become apparent froml the detaileddescription iollowing and from theaccompanyrng draw ing, setting forthand illustratirlgy the novel construction and arrangementand`combination of parts of a preferred embodiment of my invention. v l,

Fig. 2 is an'elevational view in section of the device. y Y Figlj is afragmentary view in elevation of the rnouth-'piece of thed'evice".

The saliva-ejecting device herein describedandV illustrated is of thestyle especially' aptheinlfet openings 4e, herein shown arbitrarily,

tour 1n number, through' .which the sali-va' plicable for use indentaloperations 'The device lcomprises two sections,` ay mouthpiece,iorming the upper lportion ofthe dereferring to Fig. 2, is formed of atube 2,

top', adapted to rest generally in the; region of theV mouth beneath thetongue.4 The extremity of the beak 3' is provided -with is drawn fromthe mouth.l About that 'portlon yof the bea-k thatwould come in contactwith the teeth, fispositioned the grooved flexible rubberiguad 5:pTOVided asf a means for' diminishing the dscomfortable feeling.. causedby thecontact of the mouth-Piece against the teeth, and for preventingundue.'

sliding vof the beak in 4the mouth.-

The groove `-19 is provided in the Vierm-ation of teeth' of VAthe *lowerjaw; The 'guard/5f.. is here shown o "f slit` construction, permittingit to be' readily` vslipped trom'the `mouth-ipieee.Y

tremity, 'in the sleeve 6, adapted toIrv engage in a sliding iit'overthe upper portion ofthe body l', here shown shouldered, r-iferringv tocoupling'. The lower end of' the male`member` 9 terminates in nippleextension, which 'in turn is adapted to be coupled to the flexibletubing 8, and vis permanentlyv attached thereto bythesecuring collar 10and rivetsv 11. v y tV The pin -12 of the clutching means is shown,reference beingha'd to Fig.- 2,iixedly mounted in the body of thedevice,.proxi 105' mating the top.- An ordinary screw, round oriilistered head, maybe used orthispurpose, the joint being preferablysoldered'.y v

On the top of the body l, reference ybeing had-to Fig.vv2,-therevisimnly positioned v`a A u 7 the guard' L5, *telco-operate withthe Contact over1 vor-Lrei'n'oved y 1 @+10 1 The tube .2',terminatesfat' its loweriex' nov es' ternally threaded male member 9'.ofthe compression-straining member, formed of the rubber washer 13attached over the Strainer 1li, the strainer 14 being fixed on the seatprovided for it on top ofthe body Although the strainer Vand washermaybe permanently attached together, it would be more preferablehowever, to adapt the strainer to be permanently seated Von the body 1using solder or a screw securing means, and'tol adapt therubber washerto snugly fit against the shoulder of the sleeve '6.ofthe mouth-piece,thereby simplifying the construction. The purpose of the strainer 14; inthe position as shown, is to act as ameans for catching any solidsubstance vthat may be drawnin through the inlets 1l. lTo connect themouth-piece with the body 1' of the device, the mouth-piece is manipu- Alated so that the slot 7 isbrought inr engagement with the pin 12, andthe mouth-piece twisted around so that the pin rests .at the topmostextremity of the slot. It will be perceived, reference being had to Fig. 3, that f Y theslot 7 is angled obtusely,.and terminates ina-nest-like rest. The engagement of the slotted portion of themouth-piece with the pin in the body will cause, at the coinmencement ofthe twisting action of the g mouth-piece, a compression of the. rubberportion of the mouth-piece and the top of the washer 13 between theopposing shouldered 'body 1. rIyhis compression pressure of the rubberwasher 13,'when the mouth-piece and body of the device are lockedinengagement, 'is equivalent to theV force tending'k to hold themouth-piece and body in this-relationship. By proportioning the degreeof angularity of the-angled slot 7 with the valueof thickness andquality of the rubber washer 13, this force tending -to hold themouthpiece and body locked, can be varied to suit.

The suction pressure relieving arrangement, here assumed of thecharacterof a tappet valve, is shown disposed, rreferring to Fig.` 2, centrallyinthe wall of the body 1.

fThe opening positioned through the wall of the body is shouldered toprovide the seat 15 di forthe spiral spring 16. The valve actuatingmeans comprises the tappet 17, threaded to the push-button 18. When thepush-button is actuated it will act, against the tension of the spring16, and force the tappet 17 from its seat This will result in the-introduction of a bypath for drawing air into'the passageway throughthe body 1, and so relieve, i. e., decrease, the suction pressure actingat the inlet openings 4.

From the construction of the device,reference being had to the drawing,it will be noted how readily .both the ymouth-piece and body of thedevice may be disassembled and sterilized. Y f

Although there has been described in the foregoing, a practicalconstruction embodying the principles of my invention, variousmodifications in detail will be apparent to those skilled in the artwithout departing from the scope of the invention, as set forth in theappended claims.
